Take one toilet paper (or paper towel) tube, one condom, and some
lube. Put the condom
inside the roll and stretch the opening of the condom across the opening
of the tube. Fold the end of the condom over the end of the tube and hold
with one hand.

Step 2: Pull the
end for extra pleasure

Lube well and go at it like hell. BONUS: Pull on the tip of
the condom while you jack and it feels like a blowjob.
